General description
HOFFMANN precoat filters meet even the toughest demands. Duty cycles of up to several days are achieved through special design of the filter surface. The service life is enhanced considerably when used together with a magnetic separator filtering ferritic particles and the consumption of filtration aids is reduced substantially.
HOFFMANN precoat filters operate based on the filter cake and deep filtration principles. Filtration down to 3 µ is possible.
Depending on the task at hand, our precoat filters are available in several variants:
- manual
- semi-automatic
- fully automatic
- horizontal or vertical arrangement of the filter plates

Maxflow combines filtration without filter aids - or, if they are required, with considerably reduced quantities of filter aids - and briquetting in a single unit. The main fields of application for Maxflow are particle filtration, the retrieval of recyclable materials and the purification of aqueous solutions.
Maxflow is available in three variants:
- The plug&play solution is a fast and effective solution to a great number of typical process requirements.
- Adaption of the individual components, for example by adding another filter disc to the unit.
- Implementation of a complete system, which can be custom adjusted to meet both known or as yet unencountered customer requirements.
GKD-CompactFiltration's Maxflow concept is a tried and tested serial product with the flexibility needed to be integrated into any customer-specific process. It has proven its efficiency in terms of meeting established standards and as a made-to-measure individual solution. Thanks to worldwide standardized parts and the global presence of GKD through six production facilities, the Maxflow system can be deployed anywhere in the world with equal efficiency. Comprehensive solutions competence, covering all stages from initial layout and dimensioning through to commissioning of the equipment and later expansion or modification to adapt it to changing production conditions, qualifies GKD-CompactFiltration as an efficient systems supplier and reliable technology partner in all stages of the process.

The BHS-Autopress can be used for separating moderate to poor fil-tering suspensions efficiently. Media that need to be treated in closed machines for reasons of sterility, toxicity and workplace hygiene are se-parated safely and reliably.
If required, you may also treat the cake by washing, extraction, pressing blow-out and drying. Low cake thick-ness, complete filtration without heel volume and an ex-ceptionally low level of residual moisture in the pre-dried cake ensure extremely high throughput rates.
The highly efficient cake washing process occurring in the BHS-Auto-press produces an absolutely pure product without inter-mixing. The encapsulated version (for pharmaceutical products and in GMP design) can also be used for filtering toxic or volatile media.
The BHS Autopress is made up of the following principal compo-nents:
# horizontal stack of filter plates
# movable filtration housing
# scraper
|
|
|
The BHS-Pressure Plate Filter is a pressure filter that operates on an intermittent basis and is used primarily for separating solids/ liquids in average to poor filtering suspensions with relatively low solids content, for adsorptive filtration processes (adsorption through filter cake) as well as for clarifying filtration.
|
|
The BHS-Rotary Pressure Filter is a continuously operating filter of pressure-tight design. This makes it ideal for processing volatile and hazardous products as well as for sterile processes.
Extensive subsequent treatment processes are possible, such as cake washing in one to five stages with or against the direction of flow, solids/liquid extraction, steaming, blow-out, intermediate suction, subsequent hot drying and many others. The BHS-Rotary Pressure Filter works on the principle of cake filtration and is designed for the following operating parameters:
# Pressure differences up to 6 bar
# Cake thickness up to 185 mm
# Operating temperatures up to 160°C
# Filtration capacity range 200 to 50 000 l/m²h
# Solids content from 0,5 % by weight
# Main grain size distribution 5 to 200 µm
